Diamond and gemstone reports fom Victoria James
If you have a Diamond or gemstone, mounted or unset (loose) and you would like your ring, pendant, earrings or loose stone graded then we can provide this service. We use independent gemmologists who can produce a full report or mini report on your diamond.
We use Anchorcert as an independent grader and assessor of diamonds. Anchorcert is the well respected diamond grading department of the Birmingham Assay office, here in the Jewellery Quarter. (see our Hallmarking page for bit of history on the Assay Office.) This means we can have your diamonds assessed and returned to you safely and quickly.
There are two types of Diamond report available:
Full diamond report
A comprehensive diamond report with full dimensions, descriptions, photographs, diagrams etc in the form of a full-size A4 glossy document.
Your diamond will be graded in each of the Four Cs - Cut, Clarity, Colour and Carat.
Diamond cut, polish and symmetry grade
You will be given a grade description from Excellent (best grade for all three) through very good, good, fair etc. The best grade Diamond would be described as EX, EX, EX. (for Round brilliant cut Diamonds only)
You will also receive a fluorescence grade and a girdle description.
Diamond colour
You will be given a colour grade in the form of a letter, starting from D (Best grade, colourless Diamond) through E, F, G, H etc.
Diamond clarity
You will be given a Diamond Clarity description from Internally flawless (best clarity grade) through VVS, VS, Si etc.
Diamond Carat weight
You will be given a Diamond weight from 0.20ct through to 2 or 3cts, this helps determine the size of your Diamond.
The cost of an Anchorcert full Diamond report is £70.
Mini diamond report
The mini Diamond report will give you a photograph of the Diamond, a Diamond colour grade, a Diamond clarity grade, measurement and a Diamond carat weight and comes in a neat pocket sized booklet, like a passport for a Diamond.
It is not as detailed as the full Diamond report but is sufficient enough to offer piece of mind as a third party has graded your Diamond.
A mini report is suitable for loose, mounted and multi-set diamond jewellery. This report is also UKAS accredited
The cost of an Anchorcert mini Diamond report is £45.
Tanzanite Grade mini report
In addition to our two diamond reports, we now also offer a Tanzanite mini report. Tanzanite is an increasingly popular gemstone. AnchorCert has developed a unique grading system for the Tanzanite gemstone and the report provides reassurance about the authenticity and quality of each stone submitted. This report can be carried out for loose, mounted and multi-set tanzanite jewellery.
The colour of a tanzanite is described as vivid (AAAA) Intense (AAA) moderate (AA) or pale (A). The clarity of a Tanzanite is a bit like the GIA clarity grading chart where the best clarity is described as Internally flawless, then very, very slightly included (VVS), VS, SI and included 1,2 and 3. As seen in the chart below.
The Mini Report provides weight, shape, measurements, colour and clarity as well as a digital image of the stone or jewellery piece.
The cost of an Anchorcert mini Tanzanite report is £45.
